Here’s what every Kardashian sister eats when they decide to go on a diet

I can't lie it's hard keeping up with the Kardashians/Jenners. Between sisters Kourtney, Kim, Khloé, Kendall, and Kylie, there are endless endorsements, clothing brands, beauty lines, retail stores, emoji, websites, apps, mobile games, books, and about a million shows and spin-off shows.

It really is a full-time job just to track who is doing what and when, and we haven't even gotten started with North West and her fashion trendsetting ways. One thing that seems fairly constant, however, is their dedication to fitness and healthy diets. After a lot of sifting, here is exactly what each sister is and isn't eating.

First to the plate: probably the most health conscious (konscious?!) of the Kards, Kourtney. She and her kids eat an organic, dairy-free, and gluten-free diet. And clearly, it's working for her: After three kids, she's still rocking a bikini-ready body (of course, her frequent workouts with Khloé also have something to do with it).

For breakfast, Kourtney has her three-ingredient avocado pudding (one whole avocado, a cup of coconut milk, and Manuka honey) or a banana spinach shake (avocado, banana, spinach, and almond milk). Lunch could be veggies with hummus and turkey with gluten-free tortillas or her signature salad.

Dinner is usually rice or gluten-free pasta with a lean protein like chicken or fish. Kourtney has admitted to not being much of a cook, though she does enjoy recipes out of her friend Chrissy Teigen's Cravings cookbook (think lettuce wraps and vegetable tortilla soup).

You will never see her eating dairy, bread, and refined sugars. That means no sodas or cocktails either (though tequila on the rocks, beer, or rosé do make the cut). When she does indulge, it's gluten and dairy-free candy, plus treats like pizza when in Italy, or a churro at Disneyland with the kids.

Kim follows the low-carb Atkins diet. The idea behind the diet is that when you limit your carbs, your body, which usually turns carbs into fuel, will start burning fat instead. After the birth of son Saint, Kim dropped the baby weight by following the Atkins 40, a variation of the diet that allows 40g of carbs, which gave her more flexibility while she was breastfeeding. According to Kim's nutritionist, Colette Heimowitz, Kim's diet mainly consists of three things: protein, fiber-rich carbohydrates, and healthy fats.

What this looks like on a plate? Breakfast could be eggs and turkey sausage and Greek yogurt with berries, lunch is usually a salad with grilled chicken and dinner consists of vegetables and a protein. Snacks include Atkins bars, carrots and hummus, or fruit and cheese. And like Kourtney, Kim stays well hydrated, drinking about 48-64 ounces of water.

She's strongly opposed to refined sugar and carbs but when she splurges, she really goes in. For example, Kim has Snapchatted her cheat day visits to In-N-Out, where she eats a cheeseburger, cheese fries, and a vanilla shake.

Khloé's Revenge Body is the result of intense workouts and seven meals a day. Her nutritionist, Dr. Philip Goglia, developed a plan specific for Khloe's body type that is a careful balance of protein, carbs, and fats. Her staples include lean proteins, veggies, fruits, and a lot of water.

Breakfast is usually a protein shake, made with protein powder, fruit, almond butter, and water. Other main meals include veggies, or salad with a choice of protein (think chicken or a fatty fish like salmon or sea bass). The other meals, which are more like snacks eaten throughout the day, are usually fruit or vegetables with some almonds or an egg.

Based on Khloé's body type, she pretty much bans herself from having include dairy, diet foods, soy, juice, dried fruit, breads, and sodas. Khloé has one cheat meal a week, which is cake, pizza, or pasta, depending on her cravings.

When the model is prepping for fashion week or a Victoria Secret runway show, she works out every day and relies on lean proteins, vegetables, and fruit for a low-carb Paleo diet. She also drinks a ton of detox tea. On the off-season, however, she's generally on what Khloé calls the "anti-model" diet, indulging in burgers and pizza.

Probably not wise to follow the latter - if your genes aren't as good as these girls, you'll run into some problems.

Breakfast could be eggs, avocado, and toast. Lunch usually includes brown rice with chicken. The home cooked dinner that Kendall says she "could eat for every meal" is pasta and peas. Kendall also snacks on raw veggies and hummus or apples. She hates pancakes because she suffers from trypophobia, a fear of irregular patterns or clusters of tiny holes.

Another interesting fact: Kendall's living room is painted Baker-Miller pink. Some studies suggest that the color has been shown to calm nerves and suppress appetite. In her dressing room she always has Twix, Justin's Peanut Butter, and chips and guac. She also eats Frito chili cheese chips, in case you were wondering.

Finally the youngest, Kylie. She follows a fresh and organic diet, but she also eats like a "typical teenager." It's all about moderation. She drinks Fit Tea (and is a product sponsor), on her website claims she always has fresh squeezed orange juice in her fridge and openly talks about her love of grapes and rice on social media.

Gathering most of the information from her Snapchat, breakfast usually is avocado toast or bacon or banana pancakes. Lunch is usually something healthy like a salad and a pressed juice. The young makeup mogul also loves to cook, so dinner could be anything from burgers to candied yams to chicken and veggies.

Her favs to splurge on are Mexican food, French fries, Twizzlers, Oreos, and Hot Cheetos. She never eats dairy because she's lactose intolerant. Surprisingly, though, she doesn't do juice cleanses. That's because the last time she attempted one, she gave up after a few hours and went to go eat sushi instead. Relatable.

Hope you wrote some of this down somewhere. It's going to be hard to Keep Up otherwise.
